This paper presents a brief review of our recent work investigating a novel bottom-up approach to realize silicon-based nanoelectronics. We discuss fabrication technique, electronic properties, and device applications of silicon nanodots as a building block for various nanoscale silicon devices. r 2006 Published by Elsevier Ltd.

The magnetostratigraphy of Sites 748 and 750 of Ocean Drilling Program Leg 120 is reported. About 260 sediment cubes were stepwise demagnetized with alternating fields to determine their characteristic direction of natural remanent magnetization. In general, the characteristic inclinations of the single samples have values similar to the inclination values obtained from whole-core measurements ...

A definition of distance measure between structural descriptions, which is based on a probabilistic interpretation of the matching predicate, is proposed. It aims at coping with the problem of classification when noise causes both local and structural deformations. The distance measure is defined according to a top-down evaluation scheme: distance between disjunctions of conjuncts, conjunctions...

We present a tabular interpretation for a class of 2–Stack Automata that may be used to describe bottom-up parsing strategies for TAGs. The results are also useful for tabulating other existing bottomup automata models for this kind of languages.

A comparative study across the most widely known blockchain technologies is conducted with a bottom-up approach. Blockchains are disentangled into building blocks. Each building block is then hierarchically classified in main and subcomponents. Then, alternative values (i.e., layouts) for the subcomponents are identified and compared between them. Finally, an ontology matrix summarises the stud...

The hypothesis that theories might influence observation was proposed in the important early work of Hanson (1958) and Kuhn (1962). It has been brought to a new focus by the interchanges between Fodor (1984, 1988) and Churchland (1979, 1988). Fodor has argued that perception is not cognitively penetrable, while Churchland has argued for a strong form of theory-Iadenness. This issue has led to v...

The paper considers the potential offered by lifelong learning as a tool for capacity building and development in rural areas, especially through the exploitation of contemporary technologies. The challenges and opportunities connected with small rural schools are particularly focused upon, and teachers working in them are proposed as ideal change agents potentially powerful to catalyse bottom-...
